    • A head slider for supporting a head over a magnetic disk in a hard disk drive, and a method of making the head slider are disclosed. The air bearing surface (ABS) of the head slider includes a relatively deep recess in front of a trailing pad and an island pad. A recess is formed between the trailing pad and the island pad of the ABS. In operation, the recess may reduce the peak pressure of the ABS, resulting in a reduced mid disk (MD) hump without a reduction in other performance parameters. The reduction in peak pressure may also reduce lubrication pick-up from the magnetic disk.
    • 公开了一种用于在硬盘驱动器中的磁盘上支撑磁头的磁头滑块,以及制造磁头滑块的方法。 磁头滑动器的空气轴承表面(ABS)包括在拖曳垫前面的相对较深的凹部和岛状垫。 在ABS的后垫和岛垫之间形成凹部。 在操作中,凹槽可以降低ABS的峰值压力,导致中盘(MD)驼峰减小而不降低其他性能参数。 峰值压力的降低也可以减少从磁盘获得的润滑油。
